I believe he means a manager who can alienate a fanbase like nobody's business. I think Ozzie's mouth is far worse than Bobby V's.

Ozzie didn't alienate the entire fanbase, rather a substantial portion of it. And if you want to get down to brass tacks, many Sox fans never liked his style of baseball anyway and put up with his antics because we were winning, so when things went bad and his mouth shot off with no winning behind it, those fans were easy to turn on him.

Valentine really isn't a comparison. Ozzie's first two and a half seasons plus 2008 were quality, winning us a World Series title. Valentine shouldn't have come back, much less to this fractured team, and did nothing but make them worse.

And did you hear the quote of Bobby V's backpedalling on that remark about the weak roster today? Same blather about injuries at the AAA level, blah blah blah, ... and ended with (paraphrasing here) shame on you for taking my early remarks at face value.

I think Bobby V has seen the MLB game pass him by, he can't handle the players of today, and is ready to get ****-canned.

He really has no business bashing his roster like this publicly. The sad thing is that if he gets fired, he still gets paid.

Managers get traded (see Ozzie, Lou Piniella, Chuck Tanner). If I was in the Red Sox front office, I'd give him a choice: quit, or we're going to look into dealing your contract to an independent league team I in the Yukon. Red Sox would still have to pay him, but he'd have to ride buses to get paid.

A lot of managers who really know baseball have really grating personalities and they lack patience...like Valentine. Showalter is like that too.
Madden is an exception, although he may too - grating generally shows up when losing and he hasn't lost much yet.
